3.2.3.1.3 Maintaining a healthy body weight throughout life Quiz: AQA Food Preparation and Nutrition, Unit 1

The 20 questions

1. What does a healthy body weight depend on?

   • The number of vitamins taken each day in supplement form
   • The number of hours spent sleeping each night
   • The amount of water drunk each day, regardless of food intake
   • Energy in from food balanced against energy out through activity

2. Which is a risk of carrying too much body weight?

   • Increased levels of vitamin D in the blood, causing rickets
   • Increased risk of type 2 diabetes and heart disease
   • Increased iron stores that cause anaemia in adults
   • Increased levels of calcium that weaken the teeth

3. Which lifestyle change would help a person maintain a healthy body weight over time?

   • Skipping breakfast and eating a large meal late in the evening
   • Regular physical activity and a balanced diet with appropriate portion sizes
   • Eating large portions of fried food every day to keep the energy high
   • Avoiding all carbohydrate foods to reduce the energy intake completely

4. Why does the body's energy need often fall as a person gets older?

   • Muscle mass and activity usually decrease, which lowers the basal metabolic rate
   • The body stops needing protein, so less energy is required from food
   • The body stores more fibre, which uses up energy during digestion
   • The body starts to produce more energy from water, which reduces the need for food

5. A teenager gains weight because energy intake is higher than energy expended. What is the cause?

   • A protein deficiency, where the body stores protein as fat for later use
   • A vitamin D shortage, where the body stores extra energy as bone mass
   • A negative energy balance, where more energy is used than is taken in
   • A positive energy balance, where more energy is taken in than is used

6. Which change would help a person lose weight safely?

   • Eating slightly less energy and increasing physical activity over time
   • Taking large amounts of vitamin supplements to replace all food
   • Cutting out all carbohydrates and fruit for a short period
   • Skipping meals and eating only once a day to make a large saving

7. Why is a balanced diet important for children, especially when they are growing?

   • Children need the nutrients for growth and development, so their diets should be balanced
   • Children need only fat, since it supports growth more than any other nutrient
   • Children need no nutrients because growth comes only from water and sleep
   • Children need only sugar, since it is the body's main building material

8. Which description of a healthy body weight is most accurate?

   • The highest weight that a person can carry without any loss of fitness
   • The lowest possible weight, achieved by eating as little food as possible
   • A weight that supports good health and is maintained through diet and activity
   • The weight that is recorded once at the doctor's surgery and never changes

9. A student wants to keep a healthy weight. Which approach is most likely to succeed?

   • Only drinking water and avoiding all food for the whole of the day
   • Only eating fast foods, since they are quick and filling for the day
   • Eating the same small meal every day regardless of how active the student is
   • Eating a balanced diet and keeping active as part of everyday life

10. Which life stage needs particular attention to avoid excess weight gain in later life?

    • Adulthood, when activity often falls but energy intake may stay the same
    • Pregnancy, when energy needs are lower than at any other time in life
    • Teenage years, when the body grows fastest and is most physically active
    • Early childhood, when growth is at its most rapid and needs are highest

11. Explain why a person should check portion sizes to maintain a healthy weight.

    • Large portions increase energy intake, which can lead to weight gain if activity is low
    • Large portions reduce energy intake, which makes weight loss more likely in most people
    • Large portions have no effect on energy intake, so checking them is unnecessary
    • Large portions increase the vitamin content of food, which lowers the energy in the diet

12. Which of these is a common cause of unwanted weight gain over many years?

    • Eating a variety of fruit and vegetables every day with meals
    • Eating more energy than the body uses, with little physical activity
    • Drinking enough water each day as part of a healthy lifestyle
    • Eating a balanced diet with regular exercise and healthy portion sizes

13. Which energy balance leads to a person losing weight?

    • Energy out is greater than energy in
    • Energy out is always equal to fibre out
    • Energy in is always equal to protein in
    • Energy in is greater than energy out

14. Which factor is most likely to lead to a rise in weight in adulthood?

    • A drop in activity without a matching reduction in food intake
    • A reduction in the amount of water drunk each day
    • A reduction in the variety of vegetables eaten each week
    • An increase in physical activity with a balanced diet

15. Why is regular physical activity important for maintaining a healthy weight?

    • It uses energy, which helps to balance the energy taken in from food
    • It stores extra energy as fat, which keeps the body warm during exercise
    • It replaces the need for a balanced diet, since activity uses all the energy
    • It reduces the need for water, which lowers the energy content of the diet

16. Which of these is a risk linked with being underweight?

    • Tooth decay caused by an excess of free sugars
    • Type 2 diabetes caused by a high body weight
    • High blood pressure caused by an excess of salt
    • Weakened immune response and low energy levels

17. Why is it important to keep an eye on weight changes over a lifetime?

    • Weight changes only matter in childhood, when the body is growing fastest
    • Weight changes are caused only by water intake, so they are not a health sign
    • Weight changes have no link to health, so there is no need to monitor them
    • Sudden or large changes can signal a health problem or an imbalance in energy intake

18. Which strategy supports a healthy weight for a person who sits at a desk all day?

    • Skipping all snacks and drinks to cut the energy intake completely
    • Building short walks and activity into the day alongside a balanced diet
    • Replacing all meals with sugary drinks to keep energy levels high
    • Eating larger lunches and dinners to make up for the lack of activity

19. Which statement about a healthy body weight and diet is accurate?

    • A healthy body weight depends only on sleep, not on diet or activity levels
    • A healthy body weight is achieved by eating as much food as possible each day
    • A healthy body weight is maintained by matching energy intake to energy used
    • A healthy body weight is achieved by cutting out all food groups for long periods

20. Explain why a person's body weight may increase after giving up regular exercise.

    • Energy in falls while energy out stays the same, so the body stores protein as fat
    • Energy out rises while energy in stays the same, so the surplus energy is lost as heat
    • Energy out falls while energy in stays the same, so the surplus energy is stored as fat
    • Energy in rises while energy out stays the same, so the body loses the extra as sweat
